I'm in the process of converting my current OpenHPC cluster to AlmaLinux from Rocky. The instructions provided by OpenHPC have the defaults of Ubuntu, Debian, CentOS, OpenSuse, SLES, and Rocky. But what if you want AlmaLinux? Use this template!
Your master node will already need to have AlmaLinux 8.8 installed. To convert your CentOS 8 or Rocky 8 system in place, use almalinux-deploy so you can save the hassel of reinstallation.
Copy the contents of alma-8.tmpl into a new file in /usr/libexec/warewulf/wwmkchroot or you can clone it if you have git installed on your master server:
🖥️ As root:
git clone https://github.com/cfultz/alma8-warewulf-template-ohpc/
chmod 644 alma-8.tmpl
##Setup chroot
export CHROOT=/opt/ohpc/admin/images/alma8
##Build the initial image
wwmkchroot -v alma-8 $CHROOT
Then continue following the guide as normal. You're simply swapping out the rocky-8 for alma-8.
This should work just fine (as it seems to be during my testing), but if there is anything I need to change, put in a pull request.
